IMPROVEMENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. 37,715, dated February 17, 1863.

To all whom, it may concern:

Be it known that I, S. S. WILLIAMS, of the city of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Water-Elevators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of thisV specification, and to the letters of reference marked thereon, in which- Figure l represents a perspective view of Iny improvement.

It consists of a curb, A, and windlass B, with a bucket, O, at each end of the rope T, so that the weight of one bucket is balanced by that of the other, making the resistance at all times nearly equal. At the front of each of these buckets and nea-r the bottom is a metal spout, e, projecting some inches therefrom, the opening leading to these spouts being closed by a valve, It, as seen at Fig. 2, (which represents an enlarged vertical section of a bucket, with a valve, spout, and trippingblock.) This valve R is attached to a lever, L, Fig. 2, Working on a pivot, fz', within the bucket O, and just above the opening a7. As the bucket descends in the well g the valve is opened by the force of the water entering therein, when upon the mot-ion of the-crank s being reversed the water, by its outward pressure, closes the valve and enables the bucket to be drawn up full. The lever L projecting a short distance above the bucket, the upper end, when arriving at the proper height, strikes against an incline tripping-block, fm, which opens the valve R. and allows the water in the bucket to escape. Between the bucket C, and extending down into the well nearly to the bottom, is a guide, N, which prevents them from striking each other as they pass in the well g, and also act as a guard against swinging, and at the same time insures their being in proper position to discharge the water to the front when drawn up.

To enable others to make my improved Water-elevator, I will proceed to describe its construction.

The curb A is made of wood of the usual form, the windlass B being placed tr s rse to the front. This windlass is formed by passing a small shaft th rough alarge pulley, around which the rope T is passed one turn and a half, which prevents its slipping and liability to climb.77 The buckets are nothing more than square boxes open at the top, with a water-passage through the front near the bottom, which is closed by a valve, B., made of leather, attached to an iron lever, L, working on a pivot, i, in the bucket, as hereinbefore stated. Extending from the curb is the guide N, which is a strip of wood of sufficient breadth and thickness to hold the buckets to their proper position in ascending or descending, always keeping the front of the buckets so that their spouts shall pass through the openings J in the platform I), and for other reasons previously stated. The upper end of the lever L iscurved to project over the edge of the bucket to form an inclined face next the tripping-block m, which is shaped to corresppntl thereto, This block is attached to the frame of the curb, beneath the top, which, when the ascending bucket arrives at its proper height, throws the lever forward, opens the valve, and allows the water in the bucket to run out. This I consider one of the best and most efficient plans yet devised for keepingthe buckets steady, and obviates the. strain required to empty the buckets after they have been drawn to the surface.

Having thus described my improved waterelevator, I wish it distinctly understood that I lay no claim to the parts separately considered; but

" What I do claim is- The combination and arrangement of the parts as herein specied and shown, for the purposes as set forth.

Vitnesses: S. S. WILLIAMS.
